AC Data Systems introduces the new SPECTX MTS-ATS, a Surge Protected Energy Center/Transfer Switch (SPECTX) with a field upgradable transfer switch. The UL 1008 listed integrated load center features a patented new design in switching technology from Electric Equipment & Engineering Co., which allows an in-field conversion from a manual transfer switch (MTS) to an automatic transfer switch (ATS). The upgrade requires no footprint change or load rewiring. Featuring a NEMA 1 enclosure, the SPECTX MTS measures 57 11/16 H × 24 W × 6 7/16D. The SPECTX ATS measures 57 11/16 H × 24 W × 9 1/2 D. Depending on the installation, molded case circuit breakers, with a thermal magnetic trip unit and an isolated neutral bar, eliminate the need for other breakers or fused service disconnect switches. The mechanical walking beam interlock prevents both circuit breakers from being closed at the same time. The enclosure also features the patented SurgeBlox surge suppression modules with individually fused MOV components and SAD circuits. Optional features for the SPECTX MTS-ATS units include a manual operation selector for bypassing solid-state controls and an exercise timer to cycle the generator with or without loads.
